Flying robot shows why it’s so difficult to swat a fly

If you have ever tried to swat a fly, you would have found that it is hard and you can’t do that just in one hit.

So, what’s the science behind that?

Flies rely on the laws of physics to carry out complicated aerial manoeuvres. “To avoid dange, they make clever use of aerodynamic forces so they never become unbalanced and can rapidly escape”, says Florian Muijres, researcher at the Experimental Zoology Group of Wageningen University & Research.
